Microaggregation for Database and Location Privacyicroaggregation is a special clustering problem where the goal is to cluster a set of points into groups of at least . points in such a way that groups are as homogeneous as possible. A usual homogeneity criterion is the minimization of the within-groups sum of squares. Microaggregation appeared in

Efficient Caching Strategies for Gnutella-Like Systems to Achieve Anonymity in Unstructured P2P File Most of existing technique mostly focus on how to provide the initiator anonymity and privacy, but leave the anonymity of the server. Our technique is similar to Onion routing in that it uses a proxy node to hide the identity of the client and the server. But it differs from it in that the proxy no

Conjunctive Queries over DAGsa occur in many contexts, such as ontologies for the Semantic Web and Complex Event Processing. The relations representing the DAG are binary axis relations, mostly adopted from XPath, and unary label relations. The relations definitions are generalized for the DAG case. We prove that all polynomial

Incrementally Computing Ordered Answers of Acyclic Conjunctive Queriesle for Web applications, since the result could be very large while users expect to get quickly the top-. tuples. Tractability, in this case, amounts to enumerating answers in sorted order with . under . complexity. It is proved that an efficient algorithm for finding the top-ranked tuple of a conju

Count-Constraints for Generating XMLxpressed using XPath and the aggregate function .. a DTD ., the problem of generating an XML document that satisfies both . and . is studied. Classes of count-constraints and DTDs for which the satisfiability problem is polynomial are identified. For these classes it is shown that a satisfying docum

A Taxonomy and Representation of Sources of Uncertainty in Active Systemsd by events. In many cases, however, there is an information gap between the actual occurrences of events to which such a system must respond, and the data generated by monitoring tools regarding these events. For example, some events, by their very nature, may not be signaled by any monitoring tool

Analyzing Object-Oriented Design Patterns from an Object-Process Viewpointely and correctly throughout the development process, design patterns should be classified and represented formally. In this paper, we apply Object Process Methodology (OPM) for representing and classifying design patterns. OPM enables concurrent representation of the structural and behavioral aspec
